With one day remaining in the November sweeps derby, CBS and NBC are duking it out for first place among total viewers. Based on preliminary results, CBS is maintaining a slim 160,000-viewer lead over NBC. The Peacock, meanwhile, will easily take top honors in adults 18-49, with a resurgent ABC — which saw its Bachelor finale rank No. 3 last week — edging out CBS for second place in that demo. But the big winner remains the WB, which is up a whopping 17 percent among young adults compared to November 2001.
